Aphids on tomatoes - how to process and how to fight

In early spring, gardeners of amateurs begin their chores on personal plots and gardens: prepare the soil for sowing, apply fertilizer, cut trees, grow seedlings. But worries do not stop even when all the necessary preliminary work is completed and the time for planting comes. If you decide to grow a good tomato crop, then you need to know that lush, immature seedlings require even more attention. Young, juicy, green stems at any time can be attacked by such a parasite as aphid. A small insect can quickly destroy the fruits of all your labors. In order to preserve the crop, you need to know how to deal with aphids on tomatoes.

General Pest Information

Aphids belong to the superfamily of insects, the order of beetles. More than three thousand species are known, some of which live in Europe. Size ranges from 2 to 7 mm. The insect has a proboscis, which pierces a leaf or plant. It feeds on vegetable juice, secreting a sweet liquid - a pad, which attracts ants and other insects. In all species there are winged and wingless individuals.

The pest appears in spring from larvae hatching from eggs laid in the fall on the host plant. After molting, the larvae, feeding on the juice of young shoots, begin to multiply, producing wingless females.

On a note!

These insects in one month can reproduce three generations, numbering more than hundreds of thousands of individuals. When the stems of young plants become stiff, a winged aphid appears, which flies to another place and the reproduction process is repeated again.

Despite the fact that the tops of the tomato itself is a remedy for aphids and other pests, this does not stop insects, they settle on the lower part of succulent leaves, stems of ground and greenhouse plants. The first symptoms indicating that aphids appeared on tomatoes include the following criteria:

  • deformation of leaves, ovaries and shoots, they dry, begin to crumble;
  • the appearance of sticky dew on bushes and tomatoes, a large accumulation of ants around plants;
  • cessation of tomato growth.

If aphids attacked tomatoes when the fruits are ripe, then the pests will not be able to do any damage. But, not to struggle during flowering with the aphid colony that has appeared is to lose the entire crop. Aphids on tomatoes in a greenhouse can also destroy cucumbers that are planted nearby.

Species of parasites

Several types of insects parasitize on tomatoes and cucumbers. Although the aphid looks different, the result of its activity is always the same - the death of the crop. The main pests that settle on tomatoes include:

  • potato;
  • root (white);
  • peach;
  • melon.

Potato aphids have a size of up to 4mm. The color of the body of wingless representatives is red or green. Winged individuals are light green. The danger of this species is that they damage tomato bushes everywhere: in open ground and in greenhouses.

Root or white aphids on tomato seedlings appear from the top layer of soil, where they successfully hide until the right moment.A translucent small pear-shaped body is difficult to see in the ground, since the pinkish or brownish color of the pest merges with the ground. The insect damages the stem at the base, thereby blocking the flow of nutrients and water to the top. The plant dries and dies. The eggs of the root aphid remain wintering in the ground.

Melon aphid is very small, up to 2mm in size. Wingless individuals have a color from light green to dark green, winged individuals are black and green. They are active in greenhouses in early summer, and in open ground in July-August.

Peach aphid (greenhouse, tobacco) - causes tangible damage to tomatoes growing near peach trees. In the summer, when the population grows, it moves to another type of plant - tomatoes. By the end of summer, it returns to its original place, where it remains to winter.

On a note!

Not only tomatoes are affected by these insects. Green aphids live on apple trees. Grapes have chosen red aphids. Under favorable environmental conditions, these pests attack any vegetable crops, fruit bushes and fruit trees.

If aphid appeared somewhere in the garden or kitchen garden, one must immediately begin to fight this scourge, otherwise the whole territory will turn into the living space of this pest.

Insect control

Before conducting any activities, it is necessary to decide: how to process tomatoes from aphids. There are several methods for controlling insects:

  • Biological. It consists in attracting birds (sparrows, tits, hummingbirds) to the site, which eat aphids by installing drinking bowls. Use ladybugs to clean plants from parasites. Flies, wasps, lacewings will also be happy to take part in a feast on your site, destroying gluttonous pests. Thus, aphids can be removed in a few days.
  • Chemical. Specially designed insecticides in order to poison the aphids. If the territory of the site or garden is small, then you can fight parasites with folk methods. It is more environmentally friendly and the soil remains clean. But on a large scale, this is not possible. In this case, you have to fight chemistry.
